Description

(Phaseolus coccineus) Pole bean. This bean variety is an explosion of colors and flavor, from the flaming blooms to the onyx-black beans with fabulous flavor. It dates as far back as the mid-1600s, it was first recorded by German botanist Michael Titius in his Catalogues Plantarum.

This rare runner bean produces masses of gorgeous blooms that range in color from tangerine to cherry red, making this edible ornamental pole bean irresistible to hummingbirds! The pods are shorter than those of other runner beans, and the immature pods can be eaten just like common green beans.

The pretty, plump beans change from pink to purple, and then to a pure ebony black. They cook down to a creamy texture and are fantastic when used like kidney beans.

Growing Tips, Tricks and FAQs

Growing Tips

To ensure successful growth, plant  Black Coat runner beans in full sun and provide a structure like a trellis or teepee for support. These beans prefer moderately fertile soil enriched with compost or well-rotted manure. For optimal flower set, ensure the soil is slightly alkaline; adding lime can help if your soil is acidic​.

When to Grow

Black Coat runner beans prefer mild temperatures, making them a great early-summer crop in hot areas. Plant after the last frost when the soil has warmed up. In regions with mild climates, they can be started indoors 4-6 weeks before the last frost date and then transplanted outside after hardening off. In cooler regions, direct sowing in late spring is ideal. The beans require soil temperatures between 60-85 F to sprout, and germination typically occurs within 7-10 days​​.

How to Sow and Plant

To sow Black Coat runner beans, plant them 1 inch deep in rows 2-3 feet apart. Space plants 8 inches apart. If starting indoors, use peat or paper pots to minimize root disturbance during transplanting. Keep the seedlings well-watered and maintain consistent moisture to prevent drying out. Harden off the seedlings for a week before transplanting them outside​​.

How to Grow

Black Coat runner beans need regular watering and benefit from mulching to retain soil moisture and keep roots cool. Fertilize with a potassium-rich fertilizer once the flowers appear to enhance fruit set and overall plant health. Avoid high-nitrogen fertilizers as they promote foliage over bean production. Encourage pollination by ensuring the presence of bees or hand-pollinating if necessary​​.

How to Save

This is a self-pollinating bean that can on occasion be insect pollinated. To prevent crossing between different runner bean varieties, isolate by 500 feet.

Allow pods to brown and dry. Beans are ready for saving when they are so hard that your fingernail cannot dent them.

Store in a cool, dark, dry place.

Runner bean vines also produce a tuber that can be dug in fall and saved over winter. This can be replanted in spring and plants will establish and bloom earlier.

FAQ

How do I support Black Coat runner beans?
Use trellises, teepees, or metal arches for support. Ensure supports are sturdy, as the vines can grow up to 6-7 feet tall​.

What are the common pests and diseases for Black Coat runner beans?
Watch out for slugs, snails, aphids, bean rust, and bacterial blight. Use organic methods like neem oil, copper tape, and crop rotation to manage these issues​.

How and when should I harvest?
Harvest the pods when they are 6-8 inches long and tender. Regular picking encourages more pod production. For seed saving, let some pods mature fully on the plant before harvesting the seeds​.
